I am working on my project truck, planning a turbo setup this year, but I don't have it yet. I installed a BTR 4.8 truck turbo cam, stage II. The truck will run, but starts poorly, and won't idle very well. Does anyone by chance have a base tune for something similar? Specs are:
218/223 .598/.571 112+3
I am new to the tuning world, and my plug in comes tomorrow. I really want to drive the truck till I get the turbo in, I know the performance wont be fantastic, I just want it reliable.
Thanks!
Do you have a wideband set up? You'll need that too. When you get your dongle, post a tune file and hopefully someone can help you.

I have realized that tuning is a rabbit hole. No problem diving down this hole, in fact I jumped willingly. Just want to avoid hitting every ugly rock or root on the way down it.
I dont have a wideband yet, I didn't think I needed one right away. I am looking into getting one soon, I have seen you can connect it to stock ECM on my 4.8 through the EGR input, doing more research on that.
Not sure how to post my log file.
A wideband is a must on anything GM V8 related. It's impossible to know how exactly you need to fix the fueling because these vehicles run narrowband o2 sensors.

If you don't post your tune and logs when you have questions you aren't helping yourself.
